APPARATUS FOR COVERING ROLLERS WITH TOOTHED METAL.

S PECIFICATION forming part of Letters Patent No; 277,297, dated May 8, 1883.

Application filed June 6, 1882. (No model.)

T 0 all whom it may concern:

Be it known that I, WILLIAM T. LEECH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Ooverin g Rollers with Toothed Metal, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a front view of apparatus embodying my invention. tion thereofin line 00 m, Fig. 1. Fig. 3 is an enlarged view of a portion of Fig. 2, a part thereof being sectional.

Similar letters of reference indicate corresponding parts in the several figures.

Burring, ginning, and other cylinders have been covered or clothed with toothed metal, generally termed toothed wire, but it has been found difficult to temper said metal without injuring the cylinder on which itis wound.

My invention consists of means for heating the metal or wire removed from the cylinder, and also of the provision for adjusting the heating medium.

The invention also consists of means, substantially as set forth, for retaining a uniform height of tempering-fluid.

Referring to the drawings, A represents a lathe, and B the traveling saddle thereof, employed for applying toothed wire or metal spirally on a cylinder, (shown at 0,) as well known.

D representsavertical tube, whichis secured to a frame rising from the saddle B, and adjacent thereto is a gas-pipe, E, which is also supported on the saddle B, and provided with jets F, which open or project into the tube D, the pipe E being properly supplied with gas. The tube D is so disposed that the length or piece of toothed metal or wire may be passed through it in line with the guide or roller G of the saddle without affecting the usual operation of said roller.

H represents a trough for containing the tempering-fluid, the same being secured to and moving with the saddle B, and so located that.

the cylinder 0 to be covered dips into said trough. Leading into the trough is a flexible pipe, J, which communicates with a pump, K, and in the side of the trough is formed an overflow-openingga, which is so arranged that Fig. 2 is a vertical sec-' the proper height of the tempering-fluid may be maintained. The pump K is supported on the bed of the lathe, and has a pipe, L, which dips into a longitudinally-extending tank, M, in the bed of the lathe, the rod of the pump.

being operated by an eccentric, M, which is fixed to the supporting-shaft of the roller 0 and engages with a yoke'or bifurcation, 1), whose arm or lever M is suitably fulcrumed, and is connectedwith the pump-rod. that the tube D and gas-pipe Eand the trough H move with the saddle B, and the pump K and tank M are stationary on the bed of the lathe, the trough H overhanging said tank M.

It will be seen It will also be seen that when'the toothed its temper, the efi'ect of which, besidesfitting the metal for subsequent use, renders it capable of being wound on the cylinder without liability of breaking or fracture as it is bent around the same. Thepump K is also in operation, and supplies the trough H with tempering-fluid from the tank M through the pipe .J, and as soon as the fluid rises in the trough to a level with the opening a the fluid overflows and drops into the tank M, thus maintaining a constant level of fluid in the trough, it being noticed that the fluid in the tank is returned to the trough by means of the pump K.

As the tube D is above thecylinder C, it is evident that the heating medium or flame of the gas-jets is not directed against the cylinder G, whereby the latter is notinjured by said medium or flame. The gasjets are arranged one above the other, so that the combined heat of all the flames of the jets may be directed against the toothed metal asit passes through the tube D, and it is evident that the degree of heat may be adjusted in a most convenient and reliable manner by means of the cooks or plugs of the gas-jets.

It is evident that the improvements are applicable to apparatus adapted for coveriu g rollers or cylinders with plain or untoothed metal or wire without changing the construction or operation of parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Thelathe and its traveling saddle, in combin-ation with a heating device for the metal removed from the cylinder, substantially as and for the purpose set forth.

2. The lathe andits traveling saddle, in combination with the tube D and a beating medium for the metal removed from the cylinder, substantially as and for the purpose setforth.

3. In an apparatus for covering or clothing rollers or cylinders with metal, a tube which I5 inoloses or guides the wire, and a gas-pipe with one or more jets discharging into said tube, combined and operating substantially as and for the purpose set forth.

4. The trough H, into which the cylinder 0 2o dips, in combination with tank M, pump K, and an eccentric on the cylinder-holding-shaft,

whereby said pump is operated.
